The development of physicians’ core competency is related to the quality of medical practice. Accordingly, knowing how to cultivate and evaluate core competency is an important issue for medical education and management. This study used the comprehensive core competency framework proposed by the Accreditation Council for Graduate Medical Education (ACGME) and employed fuzzy AHP (FAHP) and DEMANTEL methods to analyze the weight and priority, as well as the cause-and-effect cluster. The FAHP analysis yielded the following rankings of factors’ importance: (1) patient care (C1; 27.83%), (2) medical knowledge (C2; 20.77%), (3) professionalism (C5; 17.93%), (4) interpersonal and communication skills (C4; 17.41%), (5) practice-based learning and improvement (C3; 15.52%), and (6) systems-based practice (C6; 8.233%). In terms of the DEMANTEL, the effect cluster included patient care (C1), professionalism (C5) and systems-based practice (C6), and the cause cluster included medical knowledge (C2), practice-based learning and improvement (C3), and interpersonal and communication skills (C4). The findings showed that patient care (C1) results from attitudes, patience, and the other five ACGME Core Competencies. Furthermore, emergency physicians’ development also requires humanities and ethics training and practice to ensure practice-based learning (C3). This study demonstrates the importance of various factors in developing emergency physicians’ core competencies, and the findings may provide a reference for future attempts at such competency development.

The development of the core competence of physicians is related to the practice of medical quality. As the most important field for cultivating the core competence of physicians, how to achieve the construction and evaluation of core competence is an important issue for medical education and management. This study uses the large core competence framework proposed by the ACGME (Accreditation Council for Graduate Medical Education), and use Fuzzy AHP (FAHP) and DEMANTEL method to analyze the weight and priority, and the cause and effect cluster. Study result shows that the FAHP’s importance factor ranking is (1).patient care (C1) (27.83%), (2).medical knowledge (C2) (20.77%), (3).professionalism (C5) (17.93%), (4). Interpersonal and communication skills (C4) (17.41%), (5). practice-based learning and improvement (C3) (15.52%), and (6). systems-based practice (C6) (8.233%). In terms of DEMANTEL, the effect cluster include Patient Care (C1), Professionalism (C5) and Systems-based practice (C6), and the cause cluster includes Medical Knowledge (C2), Practice-based learning and improvement (C3) and Interpersonal and Communication skills (C4). According to finding, the patient care (C1) is the result of attitude, patience, and other five ACGME Core Competence Items. Therefore, the development of emergency physicians’ also needs humanities and ethics training and practice to follows the practice-based learning (C3). This study demonstrates to show on importance factor in emergency physician’s core competencies cultivate. Furthermore, the current findings can serve as a reference for future research in the other specialists physicians cultivate.
